BMSCs are a type of cell culture that is derived from bone marrow. They are multipotent stromal cells that have the ability to differentiate into various cell types, including osteoblasts, chondrocytes, myocytes, and adipocytes. BMSCs are commonly used in research and clinical applications related to tissue regeneration and repair.

BMSCs (ATCC)were cultured in MEMα medium supplemented with 10% fetal bovine serum (FBS; Gibco), 1% antibiotic‐anti‐mycotic solution (Gibco) and 5 ng/ml bFGF (Gibco). Osteogenic differentiation media comprised the basal culture medium supplemented with 50 μM L‐ascorbic acid (Sigma), 10 mM β‐sodium glycerophosphate (Sigma) and 10 nM dexamethasone (Sigma). MC3T3 cells (Chinese Academy of Medical Sciences, China) were cultured in MEMα medium supplemented with 10% FBS (Gibco), 1% antibiotic‐anti‐mycotic solution (Gibco). RAW264.7 cells (RAW‐OCs, Chinese Academy of Medical Sciences)were cultured in DMEM medium supplemented with 10% FBS (Gibco) and 1% antibiotic‐anti‐mycotic solution (Gibco). The generation of colonic organoids from hiPSCs (CELLAPYBIO) involved a multistep technique whereby hiPSCs were directed to form definitive endoderm, hindgut structures and ultimate colonic organoids. hiPSCs were grown on matrigel (BD)‐coated six‐well plates in mTsSR1 medium (STEM CELL Technologies). All cells were maintained at 37°C with 5% CO2.

Check if the same lab product or an alternative is used in the 5 most similar protocols
BMSCs (ATCC, Manassas, VA, USA) were maintained in a complete medium containing with 100 U/ml penicillin, 10% fetal bovine serum, and 100 μg/ml streptomycin (all from Gibco; Waltham, USA) and cultured at 37 °C and 5% CO2. Different concentrations (10-8 M, 10-7 M, and 10-6 M) of GC—dexamethasone (Dex), was added into the medium, and miR-596 expression was measured by quantitative real-time PCR (qRT-PCR). The cell morphology of BMSCs n the first and fourteenth day after GC induction was observed under an inverted microscope. MiR-596 mimics, miR-596 inhibitor, si-Smad3, and their negative control (NC) were procured from Shanghai GenePharma, Co., Ltd. (China). Following the manufacturer’s protocol, cell transfections were carried out using Lipofectamine 2000 (Invitrogen, Carlsbad, USA).

Check if the same lab product or an alternative is used in the 5 most similar protocols
The MEFs and control samples were sterilized by immersion in 70% ethanol for 10 min, and then all sides of the samples were exposed to ultraviolet light for 15 min. Then, the samples were washed with sterilized phosphate buffer solution. Mouse bone marrow-derived mesenchymal stem cells (BMSCs, CRL-12424, ATCC, Manassas, VA, USA), which were tested to be free from mycoplasma contamination, were cultured until achieving ~ 75% confluence, and the BMSCs, before passage 5, were used for an all cell assay. BMSCs were trypsinized and seeded in 24-well plates in normal growth media (10% fetal bovine serum+Dulbecco’s modified Eagle’s medium, Gibco) at a density of 5000 cells per cm2 for morphology observation and at 10 000 cells per cm2 for the osteogenesis experiments. The samples with the seeded cells were placed in a 37 °C incubator under a 5% CO2 atmosphere.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
